NORMAN — Terry Shea is a Bill Walsh disciple, the Hall of Fame San Francisco 49ers coach who believed accuracy was paramount.

Shea, who has coached quarterbacks for decades in the NFL and college, said OU quarterback Sam Bradford is as accurate as he’s ever coached.

"Nobody has been able to match Sam’s accuracy,” Shea said. "Sam’s arm strength is really good. Matthew Stafford can really let the ball out of his hand quickly with great velocity. But Sam versus Matthew, Sam can really drive the ball like he did today.”

In a workout in front of NFL scouts Monday, Bradford was near flawless on all 63 passes, including 50-yard streak routes. One pass was dropped and one was thrown slightly behind a receiver but was caught.

Shea has worked with NFL quarterbacks Trent Green, Marc Bulger, Brady Quinn and Rex Grossman. Last year he helped groom Stafford and Josh Freeman, who were first-round picks, Stafford going No. 1 overall.

"For this kind of drill you would expect at least one ball to hit the ground,” Shea said. "He had one ball hit the ground and it wasn’t his fault. Last year Matthew Stafford had at least three or four incompletions. Josh Freeman had much more than we had today. Hitting the ground one time is special.”

The head coach at San Jose State and Rutgers in the 1990s, Shea spent much of the past decade in the NFL as the Chicago Bears’ offensive coordinator for one season and the quarterbacks coach for the Kansas City Chiefs and Miami Dolphins.
